Nicole Richie and Joel Madden are bumping heads over who will take over the role of godmother to their newborn baby girl, Harlow Winter Kate Madden. Nicole would like her childhood friend Paris Hilton to be Harlow’s godmom, while Papa Joel would much rather have his future sister-in-law, Sophie Monk, bestowed with the honor.

In fact, Joel doesn’t seem to like Paris very much. (SHOCKER!) An insider tells Loosch Lips that Joel believes Paris is “a bad influence and terrible role model for kids-especially his own.” Ouch.

“He calls her a selfish, spoiled brat and doesn’t understand why Nicole still wants to hang out with her. He thought Paris would settle down when she got out of jail and start doing more charity work, but she’s still partying up a storm and going from guy to guy like there’s no tomorrow.”

“When Nicole started thinking about the role of godmother to her child, the only person she ever seriously considered was Paris. They’ve had their differences, but they have history together.”

The Loosch Lips mole is betting Joel will get his way:

“If I had to guess, I’d say Sophie will end up being this baby’s godmother. If Paris proves she’s matured in a few years, Joel might relent if he and Nicole end up having another child.”
